The bibliometric data used for calculating citation-based metrics were collected on January 12, 2026. A scientist's position in the ranking is determined by their D-index (Discipline H-index), a metric that exclusively considers papers and citation counts within the examined discipline—Computer Science in this case. This allows for a focused and discipline-specific evaluation of scholarly impact.
Scope of Research and Ranking Criteria
The ranking process began with an extensive examination of 279,971 scientist profiles across all disciplines, sourced from a variety of bibliometric databases and repositories. Specifically, 1,193 scientists in the field of Computer Science were identified and evaluated.
To qualify for inclusion in the ranking, a scientist's D-index needed to be at least 30, ensuring the recognition of only highly influential researchers. Furthermore, a majority of their tier publications had to be within the domain of Computer Science. Awards and other significant achievements in the field were also factored into the assessment.
It is important to note that the D-index threshold is dynamically set in increments of 10, depending on the estimated total number of scholars in each discipline. This methodology guarantees that the top 1% of leading scholars are comprehensively incorporated into the list. Additionally, a proximity criterion is applied such that the difference between a scientist’s general H-index and their D-index does not exceed 30%, ensuring disciplinary relevance and focus.
Verification Practices and Methodological Rigor
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of a researcher's contribution, all scientist profiles included in the ranking have undergone meticulous manual verification. Publications and citation records were cross-correlated against a wide array of trustworthy sources to ensure accuracy and validity.
While not directly influencing the ranking position, the volume of publications in prominent journals and conference proceedings remains an important secondary signal of a scientist's impact and contribution within their field.
The final position of each researcher is established using the D-index, derived from carefully aggregated data from OpenAlex, CrossRef, and supplementary sources. These databases represent the highest standards of bibliometric data quality and accessibility for the international research community.
